Abstract (en)

[origin: WO2008098403A2] In an electric machine for converting electrical energy into mechanical energy and vice-versa, comprising a movable part (k, k', f, fr, fr') and a stationary part (S, M, L, W), the movable part (k, k', f, fr, fr') is designed as an inner rotor (k, k', f, fr, fr') without a winding for transverse magnetic flux. For the purposes of magnetic flux guidance, the rotor (k, k', f, fr, fr') has at least two axially spaced apart magnetic conductors (f), and the stationary part (S, M, L, W) has in the circumferential direction of the electric machine a number of magnetic webs (S, M) which operationally interact with the magnetic conductors (f) of the rotor (k, k', f, fr, fr'). The stationary part (S, M, L, W) has at least one first winding structure (W) and a second winding structure (L) arranged between the axially spaced apart magnetic conductors (f) of the rotor.
